| Abstract: |
A Class of higher-order nonlinear neutral equation
(x(t) +x(t-f)) (n) +f (t,x(t-e))=0,t ≥ t0
is considered.We have studied the classifications of positive solutions of the higher-order nonlinear neutral equation,and obtained some sufficient and necessary conditions. |
| Key words: neutral differential equation higher-order positive solution classification |
